the advantages and disadvantages of permanent magnet variable frequency air compressor are in the era of energy saving. No matter what kind of products we choose, we will include its energy saving effect as a reference value for purchasing. In the past two years, a permanent magnet variable frequency air compressor has been newly developed in the air compressor field. This type of product has entered a higher energy-saving height with air compressor, and is currently the best energy-saving product of all types.
Now the 19th National Congress advocates a new era of energy conservation, so the market for permanent magnet variable frequency air compressors is even greater, moving towards a new era of industrial energy conservation.
The advantages of permanent magnet variable frequency air compressor:
1. permanent magnet variable frequency air compressor with stable air pressure
because the variable frequency screw air compressor uses the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter. On occasions with large fluctuations in gas consumption, it can quickly adjust the response. Compared with the upper and lower limit switch control of power frequency operation, the pressure stability is improved exponentially.
2. permanent magnet variable frequency air compressor starts without impact
since the inverter itself contains the function of soft starter, the starting current is larger within 1.2 times of the rated current, and the power frequency starting is generally more than 6 times of the rated current, the starting impact is very small. This impact is not only on the power grid, but also on the entire mechanical system.
Variable Flow Control of 3. Permanent Magnet Variable Frequency Air Compressor
the power frequency driven air compressor can only work in one exhaust volume, and the variable frequency air compressor can work in a relatively wide range of exhaust volume. The frequency converter is based on the actual gas consumption to adjust the motor speed in real time to control the displacement. When the gas consumption is low, the air compressor can also be automatically dormant, thus greatly reducing the loss of energy. The optimized control strategy can further improve the energy saving effect.
4. Permanent Magnet Variable Frequency Screw Air Compressor AC Power Supply Voltage Adaptability Better
due to the over-modulation technology adopted by the inverter, it can still output enough torque to drive the motor when the AC power supply voltage is slightly lower; when the voltage is slightly higher, it will not cause the voltage output to the motor to be on the high side. For self-generating occasions, variable frequency drive can show its advantages. According to the characteristics of the motor VF (the variable frequency air compressor works below the rated voltage in the energy-saving state), the effect is obvious for the field with low grid voltage.
5. permanent magnet frequency conversion energy-saving air compressor with low noise
most of the working conditions of the frequency conversion system are lower than the rated speed, and the mechanical noise and wear of the main engine are reduced, which prolongs the maintenance and service life. If the fan is also driven by variable frequency, the noise of the air compressor can be significantly reduced.
After understanding the advantages of the product, we should also grasp the shortcomings of the product. The following summarizes the shortcomings of the permanent magnet variable frequency air compressor:
1. Afraid of demagnetization
the motor used in the permanent magnet variable frequency air compressor is a permanent magnet motor, and the weakness of this kind of motor is the fear of demagnetization. The magnetic steel determines the demagnetization. The motor is in a high temperature state for a long time and is prone to demagnetization.
2. Maintenance is relatively troublesome
compared with ordinary compressors, the maintenance of permanent magnet frequency conversion models is relatively troublesome. During the maintenance of the head, the motor must be disassembled before the head can be disassembled. Professional tools (the rotor has a strong attraction) are also required, requiring professionals to carry out maintenance work.
Oil-free air compressor in the domestic products, with completely independent production capacity of the enterprise "Shanghai Grencklin Group". Localization in the field of oil-free air has improved the global market competitiveness of my country's air compressor products. A steady stream of "oil-free air" supplies domestic mid-to-high-end manufacturing and production gas to produce global commodities.
Oil-free air compressor to choose domestic, inexpensive, more after-sales service on an insurance. Domestic oil-free air compressors are getting better and better. The sales of mature and stable products in the domestic market are also increasing year by year. Domestic industrialization is also constantly upgrading and updating, in order to meet the demand for gas. The oil-free air compressor (full name: water-lubricated oil-free air compressor) produced by Shanghai Granklin Group is also increasing in sales in the domestic market.
When the air compressor is in use, when the air humidity is high, there will be more water after the compressed air. If the air is dry in winter, there will be less water. If it is troublesome to put it, it is recommended to install an automatic timing discharge device, and the cost of self-operation should be 300 or 400. According to the air compressor
Shanghai granklin group has many cases in the food industry. food factories that need oil-free screw air compressor can contact us for inquiry. In recent years, the food industry has developed rapidly, and the automation level of food factory equipment has also been continuously improved. Machine, electricity, gas and other integrated technologies are increasingly applied to the food industry, oil-free screw air compressor is one of them.
View detailsWater-lubricated air compressor, oil-free air compressor produced by Shanghai Granklin Group, focuses on energy-saving frequency conversion series for enterprises to save energy and provide stable oil-free clean compressed air. What are the advantages of oil free air compressor?
Is it difficult to choose an air compressor for industrial use? Among the large air compressors, the "water-lubricated air compressor" produced by Shanghai Granklin Group can achieve 250KW power on a single machine. Industrial use of oil free air compressor choose it:
In the food and beverage, medicine, precision processing and electroplating, painting, foaming and other industries of gas-assisted equipment, people with work experience should know that clean oil-free compressed air is one of the essential resources for manufacturing. Contact & ldquo
No matter what to buy, we are more valued brand, but so many brands of air compressor, how to pick out good quality in so many brands of air compressor, oil free air compressor at a reasonable price. The average person has three choices.
Water lubricated air compressor manufacturers looking for granklin group, your choice will not be wrong. Our granklin group has been deeply developing water-lubricated air compressor technology and has a number of patents. If you are interested, you can also visit our group headquarters.
View detailsThe difference between oil-free air compressor and oil-free air compressor is: different materials, different final discharge of gas, and different life. Different 1. materials: 1. Oil-free air compressor: the material of oil-free air compressor contains oily substances, which will pollute the terminal equipment; 2. Oil-free air compressor: the material of oil-free air compressor does not contain oily substances, thus avoiding the pollution of oil-free air compressor to terminal equipment.
